Constructing geologically accurate reservoir models of deep-water strata is challenging due to the reliance on incomplete or limited resolution datasets.
The project involves a group of 5 professional geologists aimed at studying the sedimentation, diagenesis, and reservoir architecture and quality of syn-rift Miocene deep-water strata in the Midyan area, northwestern Saudi Arabia.
Therefore, reservoir characterization of deep-water strata must be based on direct examination of the rocks and related process-specific facies interpretations, not on wireline logs or on seismic profiles and related process-vague facies interpretations.
Nonetheless, this feeding was originally assumed to have taken place in shallow-water environments of Fossil Lake or in nearby freshwater streams feeding into the lake [1], [5], despite the rarity of its body fossils in shallow-water strata [24].
Additional baseline information is required for groundwater present in water bearing strata both up-gradient and down-gradient of the proposed operation.
The overlay/index methods use location-specific vulnerability indices based on the hydrogeological factors controlling movement of pollutants from the land surface to the water bearing strata.
Groundwater vulnerability was evaluated using hydrogeological factors that can influence the pollutant transport through the vadose zone to the water bearing strata using GIS-based DRASTIC (Aller et al. 1987) method.
Tunneling shield, machine for driving tunnels in soft ground, especially under rivers or in water-bearing strata.
Typically, 10 to 20percentt of the precipitation that falls to the Earth enters water-bearing strata, which are known as aquifers.
Some sandy layers of the lacustrine beds act as aquifers (water-bearing strata of permeable rock, sand, or gravel), and springs occur in the Kāthmāndu Valley where the sands outcrop.
